Donald Trump’s decision to bomb Syria was influenced by his daughter, Ivanka, being “heartbroken and outraged” at the country’s alleged chemical weapons attack, one of the president’s sons told a British newspaper.

The president launched 59 cruise missiles at a Syrian government air base he alleged was involved in a chemical weapons attack that killed dozens of civilians last week.

Trump’s 33-year-old son, Eric, told The Daily Telegraph on Monday that the strike was influenced in part by Ivanka, who he said was “heartbroken and outraged” by the chemical attack.

“Ivanka is a mother of three kids and she has influence,” Eric Trump said, speaking with the newspaper at Trump Turnberry golf resort in Ayrshire, Scotland. “I’m sure she said, ‘Listen, this is horrible stuff.’ My father will act in times like that.”
